Re: RE: RE: MAKE - problem with small/capital letters in filenames
Hi! If the options to allow case-insensitive globbing are present, all you have to do is turn them on (using the MAKEFLAGS environment variable for make, and the appropriate .*rc file for the shell, IIRC). I see. I'll try to find this option. If these options are not available, there are still a few ways to fix this. One is modifying your makefile to include both %.d and %.D as targets *every time* you need globbing. Doesn't work. HELLO.D generated, but 'no rule ot make target hello.d'. Another is keeping files on a local drive and using either rsync or cvs to synchronize it with the network drive If nothing else work I'll try this.

Zoltan, In the Windows filesystem, there is indeed no difference between lowercase and uppercase letters in filenames (unless the Posix option is turned on under NT, but it probably isn't in your case). Cygwin has an option (in the CYGWIN environment variable) that controls whether it recognizes wrong-case filenames. The option is check_case:mode, where mode is one of strict, relaxed, and adjust. You can read up more on this in the User's Guide. From the information you provided, it seems you have it set to either relaxed or adjust (or unset, which defaults to relaxed, IIRC). The check_case option, however, will only have effect if you try *opening* the file. The %.d construct in Makefiles performs another action on filenames, called globbing. The globbing (same as the shell's *.d) is not performed by Cygwin, but rather by the shell (or, in your case, make itself). Since the Cygwin ports of shells and make use stock Unix code as their base, there is no provision for globbing files with the wrong case (unless one was specifically put in, which I doubt). There may be options to control this, however, of which I'm not aware, so do read the man and info pages. This explains why hello.d works, but %.d doesn't: when the target is hello.d, make tries to open (or stat) the file using Cygwin's system calls, and thus ignores the case (provided check_case is set appropriately). When the target is %.d, make tries to glob all filenames that end in .d (not ignoring case), and thus doesn't find your HELLO.D. You can test this using ls in a shell (bash, in this case): $ export CYGWIN=$CYGWIN check_case:relaxed $ ls hello.c $ ls Hello.C Hello.C $ ls *.C /bin/ls: *.C: No such file or directory $ If the options to allow case-insensitive globbing are present, all you have to do is turn them on (using the MAKEFLAGS environment variable for make, and the appropriate .*rc file for the shell, IIRC).

Another is keeping files on a local drive and using either rsync or cvs to synchronize it with the network drive (you'd have to set up a repository on the network drive for cvs, of course). And the third way, if you're feeling adventurous, is fixing the Cygwin ports of your favorite shell and make to allow case-insensitive globbing, and contributing the patches through this list to benefit the whole comminity and immortalizing your name in the archives as the guy who made globbing case-insensitive. :-D Igor -- http://cs.nyu.edu/~pechtcha/ |\ _,,,---,,_[EMAIL PROTECTED] ZZZzz /,`.-'`'-. ;-;;,_[EMAIL PROTECTED] |,4- ) )-,_. ,\ ( `'-' Igor Pechtchanski '---''(_/--' `-'\_) fL a.k.a JaguaR-R-R-r-r-r-.-.-.

RE: RE: MAKE - problem with small/capital letters in filenames
Eventually, a gratefully accepted patch to the User's Manual (or FAQ) will be submitted that includes Igor Pechtchanski's detailed explanation, and we'll be able to simply point questioners to it with a URL.
